Why is the helium atom's nucleus postively charged?
Anything that is positively charged means that it has an extra number of protons. 1. PROTONS = Positive 2. NUETRONS = Neutral 3. ELECTRONS = Negative The Helium atom could have 6 protons, 5 nuetrons, and 5 electrons. The extra proton would make the atom Positive. Anything that is positively charged means that it has an extra number of protons. 1. PROTONS = Positive 2. NUETRONS = Neutral 3. ELECTRONS = Negative The Helium atom could have 6 protons, 5 nuetrons, and 5 electrons. The extra proton would make the atom Positive.
What is an atom the has a different number of nuetrons than other atoms of the same element?
An isotope.
How many nuetrons are in protactinium?
Each isotope has a different number of neutrons.Number of neutrons = Mass number of an isotope - 91
Where are proton neutron and electron located in an atom?
protons and nuetrons are in the nucleus.electrons are in the electron cloud surrounding the nucleus
What is true about the number of protons and nuetrons in an isotope?
Isotopes of an element have same number of protons and different number of neutrons. Hence similar in chemical properties and different in physical properties.
How many nuetrons to every proton is there in magneisum?
the answer is 2,8,1
Isotopes of uncharged elements have different number of what?
nuetrons
What is the number of protons an atom has?
most of the time there are two but if you have a positively charged atom there are just more protons than electrons or neutrons MASS IS ALWAYS PROTONS PLUS NUETRONS SO IF YOU KNOW THE MASS # AND THE NUETRON # AND SUBTRACT NUETRONS FROM MASS YOU GET THE PROTON # ALSO THE PROTON # = TO THE ELECTRON # AND THE ATOMIC #
How many nuetrons does selenium have?
Neutrons = Mass number (Se-80) minus Atom (or proton 34Se) number (34) = 80-34 = 46 neutrons
What is the name of the atoms that have the same number of protons and different number of nuetrons?
They are called isotopes.

How many electrons protons and nuetrons are in hydrogen?
One Proton One electron zero neutrons
Do atoms have nuetrons?
Yes they all have except Hydrogen. H has only one proton in its nucleus.
What is the number of electrons in an atom that is neutral atom with 30 protons and 34 nuetrons?
the no of electrons in a neutral atom is equal to the total no of proton so no of electron is equal to 30.
What is an atom the has a different number of nuetrons than other atoms of the same element?
An isotope.
How many isotopes does phosphorus?
Have different atomic mass (have different numbers of neutrons)
How many nuetrons does protactinium have?
Each isotope has a different number of neutrons.Number of neutrons = Mass number of an isotope - 91
